Best Mic Cover for the Shure SM7B (UK Guide, 2026)

The Shure SM7B is the most-used podcast microphone on the planet — but the stock grey foam that ships with it is, frankly, the same one Joe Rogan has used for a decade. There's nothing wrong with it. There's also nothing right with it. If you spend any time on camera, the SM7B's windscreen is the single largest piece of dead space in your shot, and it's blank.

This is a quick, practical guide to choosing a better SM7B mic cover — what fits, what doesn't, and what UK creators actually use.

Why the stock SM7B foam isn't enough

The SM7B comes with two foam options out of the box: the standard close-talk windscreen (about 70mm tall) and the larger A7WS pop-killer (about 100mm tall). Both do their job acoustically. Neither do anything for your brand.

Three problems with relying on the stock cover:

1. It dates fast. Every podcaster you've ever watched is using one. Your channel doesn't look distinct.
2. It absorbs your lighting. Grey foam reads almost-black on most camera setups, dragging the centre of your shot down a stop.
3. You can't tell your shows apart. If you run multiple shows on the same setup, every episode looks identical.

What size cover fits a Shure SM7B?

For the standard windscreen replacement, you need a foam cover with:

• Internal diameter: ~52-56mm
• Height: 65-75mm
• Cell density: medium-open (too dense kills high frequencies)

For the A7WS-style large pop-killer replacement:

• Internal diameter: ~55mm
• Height: 95-105mm
• Acoustic foam, not decorative foam — this matters

If you buy a generic "60mm foam cover" off Amazon, it'll fit physically but it'll be either too tight (squeezing the capsule housing) or too loose (rotating as you talk). The SM7B has a slightly squared-off head — covers designed for it are tailored to that shape.

Custom-printed vs branded vs solid colour

You've got three real options:

1. Solid colour custom foam

Cheapest entry point. Pick a colour that matches your brand, ditch the grey. Most people who upgrade from stock land here and stop. Cost: £15-25.

2. Branded foam with your logo

Your logo printed on the foam. This is what >80% of professional podcasters and YouTubers use once they've grown past 10k subs. Cost: £20-30. We make these for the SM7B — turnaround is 2-3 working days from London.

3. Mic flag (square or triangular)

A separate cube/triangle that sits below the mic, large surface area for branding. Doesn't replace the windscreen — sits alongside it. Suits broadcasters and conference setups.

What to look for before you buy

If you're buying a custom SM7B cover from anyone (us or otherwise), check:

• PU foam, not PE foam. PE is the cheap stuff used for shipping — it tears. PU lasts years.
• Print method: dye-sublimation or screen print, not iron-on transfer. Transfer prints crack within months of being squeezed against the mic.
• Made-to-fit, not "fits most mics". If a listing says it fits 12 different microphones, it fits none of them well.
• Sample first if you're spending over £40. Most reputable UK shops offer a single-cover sample order.

Sound: does a custom cover affect audio?

This is the question nobody answers honestly. The short answer: the foam composition matters, not the print.

A correctly-spec'd PU foam custom cover sounds identical to the stock Shure A2WS — we've measured it on a frequency analyser with the same vocalist. If anything, our covers run slightly more transparent at 2-4 kHz because we use a slightly more open cell structure.

Where you'll lose audio quality:

• Too-dense decorative foam (rolls off above 6 kHz)
• Faux-fur exterior on a windscreen (kills 4 kHz onwards)
• Anything advertised as "shock-absorbing" — these are usually too dense

Where UK creators buy

You've got three real options in the UK:

1. Direct print shops like IT Wheel (London, 2-3 day turnaround, 4.8★ from 354 Etsy reviews, made-to-fit per mic model)
2. Etsy generalists — variable quality, 1-3 week turnaround, often imported
3. Amazon "fits all" generic covers — fast delivery but rarely fits SM7B properly

If you're serious about your setup, the gap between a £20 made-to-fit custom and a £6 Amazon generic is enormous. You'll see it on camera within a single recording session.

Quick spec recommendation

If we're picking for a typical podcast SM7B user with reasonable lighting, on camera, brand-aware audience:

• Cover type: PU foam standard windscreen replacement (52mm internal)
• Height: 70mm
• Print: dye-sublimated, full-colour logo, brand-matched background
• Material weight: medium-open cell

That's basically the SM7B PU Foam Custom Cover we make. Not because we're selling it to you — because that's the spec that works for the SM7B specifically.

Bottom line

The SM7B sounds like the SM7B regardless of which cover sits on it. The cover's job is brand and lighting, not audio. Spend 20-30 quid once, get a year of better-looking shots, stop being mistaken for the generic-grey-foam podcast tribe.

Made in London, ships in 3 days. If you're outside the UK, we ship internationally but turnaround stretches to 7-10 days.
